ABSTRACT
An apparatus for the measurement of vapor pressures of pure solvents and solutions at different temperatures is described. The apparatus is tested for the temperature range (298.15 to 363.15) K using pure water and aqueous NaCl solutions. The vapor pressures are presented for methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, and 2-butanol, ranging from temperatures 298.15 K up to the boiling points of these alcohols. The vapor-pressure data of pure alcohols are correlated with the Antoine equation. The results are compared with literature values.
